Approximately one-third of renal cell carcinoma (RCC) is recognized in its metastatic stage. This systematic review aimed to summarize knowledge on the occurrence and treatment of testicular RCC metastasis. The literature search was performed by two authors independently, with the use of main electronic medical databases (Science Direct, Web of Science, and PubMed) until March 2023 to identify relevant articles that could potentially contribute to this review. Neither language nor publication dates were set as limits. Although we found a total of 51 case reports, only 31 of them contained all the required information. Testicular metastasis in patients with RCC suggests a late stage of the disease. Moreover, it usually does not present typical systemic or specific symptoms except for swelling and enlargement of the affected testis. Knowledge of the possibility of such variants of RCC metastases will allow a clinician to make an appropriate diagnosis and implement adequate treatment without delay, which is crucial in the management of neoplastic disease.

Introduction: There is no standardised, universal method to assess physical conditions such as pressure in the pelvicalyceal system in real time during RIRS (retrograde intrarenal surgery). Therefore, the problem of increased pressure in the upper urinary tract during the procedure is underestimated. Moreover, it can potentially cause micro-damage and longer postoperative recovery. The aim of this study was to evaluate intrapelvic pressure (IPP) during RIRS procedures. Materials and Methods: The 3D printed models of the pelvicalyceal system were printed based on a CT scan of the real patient. They were used to perform 50 RIRS procedures with laser lithotripsy of artificially synthesised kidney stones with two different sizes of ureteral access sheath-UAS (10/12Fr vs. 12/14Fr) together with different energy settings generated by the holmium:YAG laser. IPP monitoring during RIRS was performed with the use of the PressureWire X Guidewire compatible with the CoroFlow system. Results and Conclusions: The results showed that a high IPP of up to 400 cmH₂O would be achieved using a 10/12Fr UAS, while the use of a 12/14Fr UAS would significantly reduce the peak pressure to approximately 100 cmH₂O; hence, the size of the UAS is a pivotal factor of the IPP generated during the procedure.

Tension-free mesh hernia repair has become the standard procedure in inguinal hernia repair. The incidence of inguinal hernias has steadily decreased following mesh and laparoscopic techniques, but the potential risk of fertility disorders after surgery remains a controversial issue. The aim of this chapter was to establish the clinical impact of open (mesh and/or without mesh) and laparoscopic hernia repair on male fertility. The results of the research published to date do not allow clear conclusions and guidelines in hernia surgery for young patients of reproductive age. Evidence is inevitably difficult to find because of the wide range of causes of infertility and their complexity. However, the choice of method and the possible impact on fertility should be discussed with the patient before surgery. Additionally, preoperative and postoperative semen analysis will help exclude or confirm its impact on patient fertility in the future.

Background/Objectives: Routine local gentamicin irrigation has been used during artificial urinary sphincter (AUS) implantation despite limited procedure-specific evidence. We evaluated early outcomes after its calendar-defined discontinuation. Methods: This single-centre retrospective before–after cohort included 173 uncoated AMS 800 procedures in 164 men: 59 under a gentamicin-containing local protocol and 114 after gentamicin withdrawal. Saline device immersion and Betadine-containing intraoperative irrigation of the operative field and both wounds continued in both periods. Clinician-recorded surgical-site infection (SSI) within 90 days was the antimicrobial outcome of greatest direct relevance. Complete explantation within 90 days for SSI and/or urethral erosion was an exploratory device-related endpoint; all-cause complications at 30 and 90 days were secondary safety outcomes. Results: SSI occurred after 1/59 (1.7%) gentamicin-protocol and 2/114 (1.8%) gentamicin-free procedures (risk difference +0.1 percentage points, 95% confidence interval −7.4 to +4.7; p = 1.000). Erosion occurred after 0/59 and 4/114 (3.5%) procedures; all four led to complete explantation. The explantation endpoint occurred after 1/59 versus 4/114 procedures (risk difference +1.8 percentage points, 95% confidence interval −5.8 to +7.2; p = 0.662). Thirty-day all-cause complications occurred after 14/59 versus 16/114 procedures and 90-day complications after 15/59 versus 26/114. Conclusions: No statistically significant between-period difference was detected in SSI, exploratory device-related explantation, or broad all-cause complications. Sparse events, wide confidence intervals and calendar-defined exposure amid concurrent era changes preclude conclusions regarding equivalence or absence of clinically relevant benefit or harm.
